Once upon a time, an old Hawaiian surfer told me that those surfers who
measure from the back have already missed the wave. Of course, you could
argue that surfers who measure the wave from the back do so on purpose so
that they can purposefully underestimate their size. But why would anyone
want to do that you ask? Perhaps they are the macho guys. "Shucks ma, that
overhead wave is only three feet, at least to me. Its no big deal". But
then one day a wise guy like me comes along and says, "Three feet, for an
overhead wave? What are you anyway, only three feet tall?" The 56" surfer
says, "Huh? What? Are you blind?" "No" I say," maybe you are blind. That
overhead wave was way over your fully upright body." "Hey man," he tells
me, "you measure waves from the back." I say, "You mean the back of the
wave you cant see?" And of course he says, "Right on, dude, right on"

Wish that all this banter was much ado about nothing, but unfortunately it
is not. There is a history and a very good reason why so many surfers these
days measure from the back. Lets go back about 40 or 50 years in Hawaii and
revisit the golden years of surfing and try and find the answer. Back then
waves were bigger, bluer, and much less crowded. Surfers at Waikiki rode
huge waves all measured from the front. Duke Kahanamokus famous 1.1mile
ride had to have been 20"plus when it first broke at first break (out near
Castles). Today's surfers would have called it 10had they been there.
Trouble is, had they been there, they would not have been able to see the
wave, at least not from the beach. So how did all this back of the wave
nonsense get started anyway?

I was surfing the North Shore in those days, the late 50s, 60s and 70s, and
what started to happen very slowly over this time period was a gradual
tendency to underestimate waves. As it got worse and worse, everyone
started realizing that the smaller the estimates were, the smaller the
reports were on the radio and TV, and fewer and fewer people were showing
up to surf on any given day. Hey, man, this was way cool. A super cool
method began to develop to keep the surf a secret. Eight to 10waves at
Sunset slowly became 4-5with a few pulses. But how in Gods name could
anyone call an 8wave 4, or a 10wave 5? Not that difficult. The surfers and
lifeguards simply invented an new system of measuring the waves from the
back. It worked great, because, of course, waves from the back are about
half their size from the front. Since few people could actually see the
backs of the waves, few people could disagree or claim otherwise. Fewer
Townies went to the North Shore and the local guys had the waves all to
themselves. The lifeguards liked it too, because they had fewer people to
guard and so they could go surfing longer. The system prospered and more
and more surfers grew up believing that measuring the waves from the back
was the way to do it.

End of story. There were a few old-timers around who remembered the old
way, the first way, the simple way, the face-value,
from-the-top-to-the-bottom way, from the front, from the
crest-to-the-trough, the way oceanographers define wave height, the way in
which ordinary people can judge a wave simply by looking at it. By its face
value. Not only did the old-timers remember, but they also reminded the
lifeguards about safety. It wasn't to safe to broadcast to Hawaii's tourists
that 8-10waves were only 4-5. People drowning and getting slammed into the
bottom by shore break could sue, and guess what, they did sue. A number of
visitors throughout the Islands suffered severe neck injuries producing
paraplegia and quadriplegia, all caused by shore break waves that were
larger than those reported. Several cases were settled or won to the tune
of millions of dollars. It was not long before the City and County of
Honolulu was under a powerful economic and legal gun to change the system
back to the old way of measuring waves from the front by the face. This old
way is now called the "new" way, because so many young surfers never heard
of the old way, until now perhaps.

The "new" has been adopted by the National Weather Service in Honolulu and
is now reported by all of Hawaii's news media: newspapers, radio, TV
everyone. Even the lifeguards are now reporting face values. A special
course in how to measure and report surf was designed by the National
Weather Service tailored specifically for the lifeguards of the City and
County of Honolulu. Over the course of about 15 months (in 2000 and 2001)
about 80 lifeguards successfully completed the class. With this new
awareness, the lifeguards have embraced the "new" policy. And, there is no
question that their first and foremost concern is safety for Hawaii's
visitors and residents alike. Its been a rapid transition back to the old
way, the simple way, the safe way, and the HONEST way. Its just like my old
Hawaiian friend said, "Never measure the wave you missed. Its the one you
ride that counts".
